I just plan on popping in on Friday night to see Trish and Lita get pics with them and leave as I have a 2 hour drive back home.Any advice from convention veterans that I should know?How early should I arrive if they start at 5?

If you want to get in the actual hotel lot, you'd have to get there super early, if it's even open at all anymore.

If you're there by 3 or 4 at the latest on a Friday, you should be able to get a semi-close spot on the road behind the hotel. At the last show, they also had parking open in that close lot on the opposite side of the road, by the water, in the back of the hotel.

Worst case scenario, you'd still find a place to park, but just have to hike a mile down that back road to the con, but you will still find a spot.
